"Nowadays, ethnic minorities in Vietnam are still coping with serious difficulties in life such as poverty and illiteracy. Meanwhile, media for ethnic minorities, including radio and TV for ethnic minorities in Vietnam, are at a low level of development. In fact, both VTV5 (the TV division for ethni ... c minorities, belonging to the national TV station VTV) and VOV4 (the radio division for ethnic minorities, belonging to the national radio station VOV) have made a lot of effort to produce suitable programs for minorities but there remain limitations in both content and the ways used to express the content of those programs. The reasons come from difficulties in both radio and TV stations and minorities. However, roles of radio and TV in the life of ethnic minorities in Vietnam are obviously increasing quickly and are displayed more and more effectively. I focused on the two main roles of radio and TV as educational instruments and as instruments for assisting minorities in preserving their identity, highlighting their effects in preserving minority languages and cultures."
